Updated without issue. Not trying to rub salt in the wounds of those whose update failed, just pointing out that the majority of people have probably updated without issue. No one complains when things work.

Thanks for the idea to rent a body to do the firmware update. I want to grab one of these lenses soon, and am assuming that what is in stock now is probably the old firmware. My newest body is a 40D, so I'll have to see if I can get my local camera shop to help me out with with the update. Maybe I can give them $20 for 10minutes use of one of their bodies.

It's probably worth it to find the shop that services your local professional photographer population and make nice with them. The shop I use probably wouldn't charge me to borrow their display 5d3 to do a lens update in store.

If you live in a large enough metro area, finding a repair shop that services Canon may give the same benefit.

Why not to send it to Canon? It has to be covered by warranty, it's not yiur fault the lens has a bug...

Getting same error on 5D3. Can't update. Removed lens, reformatted card, downloaded again, same errors. stalls at about 66 % or get the thousand percent number.(on a Mac by the way). Removed lens, and battery grip, was able to get out of the try again cycle and all ok with other lenses, so far. Pancake a bust for now.

Update: seeing some comments in other forums that install issue might be related to Mac and Mountain Lion and additional hidden file?
